Need a hot wire from ac compressor

I'm wiring up electric cooling fans on a 1995 f150 4x4 4.9l and I need a hot wire from the ac. Can someone please let me know which one wire it is?

Should be able to look at the wire colors on the plug for the AC compressor.
I'm thinking black/yellow stripe.

Disconnect wiring harness at AC compressor. Turn truck on and turn AC on. Use a multimeter or test light and connect one lead to ground. Probe both pins of the wiring harness. One of them should indicate 12V on the multimeter, or make the test light light up. That's the wire you want.

The Dark Green/Orange wire is hot whenever the A/C is selected and the compressor is engaged. If you want the fan(s) to run continuously when A/C is selected use the Pink wire on the input side of the low pressure/clutch cycling switch.
